My goodness! It was the fricking internal oscillator.... I can’t express how grateful I’m for all your help. It was driving me nuts!
Well, you learn something new every day, ;)

The SWD problem should be another story, but at least now I can flash my own binary.

Again, thank you very much indeed!!
